Correction to "Detecting distortions of peripherally presented letter stimuli under crowded conditions"

We discovered a bug in the code producing radial frequency distortions for our paper

Wallis, T. S. A., Tobias, S., Bethge, M., & Wichmann, F. A. (2017). Detecting distortions of peripherally presented letter stimuli under crowded conditions. Attention, Perception, & Psychophysics. https://doi.org/10.3758/s13414-016-1245-x

In this correction, we fixed the bug, remeasured data for Experiment 1 from the paper, and found that our substantive conclusions remain.
